CORN-HARVESTER.

SlZEGliFICATION forming part of Letters Patent No. 681,147, dated August 20, 1901.

" Application nea May 7,1900. serial No. 15,866. or@ modern To ald whom it may concern:

Beit known that I, JOHN A. STONE, of Chicago, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in Corn-Harvesters, of which the following is a full description, reference invention.

being had to the accompanying drawings, in

` which- Figure 1 is a perspective View of such parts of a corneharvester as necessary to show my Figs. 2 and 3 are details. Fig. 4

" 1 is a side elevation of the parts shown in Fig. l. In that class of corn harvesters shown in `the patent granted to me December 26, 1899,

a i I5. i cutis operated upon, in consequence of which No. 640,046, the row beside that previously l the gathering devices are nearer the grainsidewheel than the other.

Because of this it is usually only necessary to raise and lower l' ao raised and lowered more than its mate.

`the machine at the grain side; but in doing so the gatherer nearer the standing corn is Its mate is not shown in the present drawings,

`because the invention as shown is applica- 1 25 to the one shown, so as to regulate the posible to one` or both, but necessarily more so tion of its point relativeto the ground, as its vertical adjustment is greater than that of its mate.

In the drawings, A is the grain-wheel of a corn-binderas one part with the arm B, piv-` E oted to the main supporting-axle B of the machine.

`main supportingaxle and other parts. this bracket is secured the forwardly-extending bar c.

` C is a bracket secured to the main frame, adapted to sustain the grain-side, end of the To c and c2 are upwardly-extending posts that are secured at their lower ends to the frame, and to theupper end of the post of is secured i the rear end of the main `supporting-board d' i ofthegathering device in the ordinary manelevated positioh above and beyond the main or platform frame of the machine, the upper end of [the post c being turned over at an angle, as shown at ci, to afford a proper connection.

D is the upper board of the grain-side gathering device; d, the flexible point of the said device.`

d is the main supporting-board of the gathering device, carrying the chains operated by the usual sprocket-wheels cl2. The post which supports the rear end of the gathering device and the means whereby the gatherer is fastened to the upper end thereof is sufficiently iiexilole to allow the small amount of movement at this point that is required by the adjustment of the forward end of the device.

Upon the bracket C and in the arm es of the main frame is journaled the screw E as one part with the crank-shaft c. As one piece with the arm B is the segment E. When ro-V tating the screw E, the arm Bis caused to move in the arc of a circle, as shown in dotl Ated lines in Fig. 2, and the grain side of the machine thus raised4 and lowered upon the supporting-Wheel A.

Lowering the machine-sayfrom the position shown in Fig. 1 to that shown in Fig, 2 the forward end of the gathering device would be moved too near the ground if no provision to avoid the same were made. As one piece with the arm B is the lug F, having the eye f, into which is hooked the link f. Upon the forward end of the bar c in the casting G is journaled a rock-shaft I-I, having the arms h and h'. The link f is hooked into an eye at the upper end of the arm h. Secured to the board d (see Fig. 3) is the bracket I, pivoted to a suitable bracket i upon the arm h'.

The operation of the device is as followsi With the parts in the position shown in full lines in Figs. l and 2 and in dotted lines in Figs. 2 and 3, if the screw then be turned the A rod f will be drawn and the arm h moved to the position shown in full lines in Fig. 3. Through the instrumentality of this rockshaft and its arm h' the gathering device will be raised relative to the body of the machine as the latter is moved toward the ground. It' desirable, the entire gathering device of a corn-binder may be controlled as here shown.

What I claim as my invention, and desire to secure by. Letters Patent, is-

l. In a cornharvester,the combination with the frame of the machine and its supportingwheel, of a gathering device pivotally con- IOO nected to the frame so. as torise and fall at its forward end, means for raising and lowering the frame on the supporting-wheel, and meansfor concurrently raising and lowering the front end of the gathering device in 0pposition to the movementI of the frame.

2. In a corn-harvester,the combination with the frame of the machine and its supportingwheel, of an arm pivotally connected to the frame and carrying the axle of the supporting-wheel, a gathering device pivoted to the frame so as to rise and fall at its forward end, means for adjusting vthe wheel-carrying arm so as to raise and lower the frame on the wheel, and a link connecting the gathering device with said arm so as to raise and lower the front end of the gathering device concurrently with and in opposition to the elevation or depression of the frame.

3. In a corn-harvester, the combination with the frame of the machine and its supportingwheel, of an arm pivotally connected'to the frame and carrying the axle, said arm having a gear-segment attached thereto, a gathering device pivoted to the frame so as to rise and fall at its forward end, ahand crank-shaft mounted on the machine-frame and having a JOHN A.
